The paper deals with methodological aspects of the comparative study of computer games as a developing form of narrative communication. The impact of fictional worlds materialised through a computer game is enhanced by the game's progressional and interactive features. This is what gives computer games obvious advantage over stories and other narrative genres. The subject matter of the existing computer games is predominantly of Anglo-American and Celto-Germanic provenience; computer games on Central European themes have admittedly been in short supply so far.
